Deep Throat a fixture in Nixon files

The National Archives released more than 10,000 pages of documents from the Nixon presidency on Wednesday and among them are the urgings of past and present FBI agents and other interested citizens to appoint Felt, then the No. 2 FBI official, as director. Associates described his "outstanding loyalty."
